DIES FOR MAKING CAN NOZZLES.

Application filed January .7, 1927. Serial Ho. 159,706.

This invention relates to improved dies or forming devices which may be adapted for various purposes but which are. particularly intended for manufacturing can nozzles or other similar devices having beads at the ends thereof which are formedby turning the metal inwardly instead of outwardly.

The objectsbf this invention areto provide improved dies for forming articles of sheet metal; to provide improved dies for making can nozzles; and to provide such other novel features and improvements in construction as will be described more fully hereinafter. a

In the accompanying drawings illustratin a preferred form of this invention;

igure 1 is a sectional view;

Figure 2 is a plan view of the lower or male die;

Figure 3 is an enlarged sectional detail illustrating the forming operation;

. Fi ure 4 is a View similar to Figure 3 showlng the completed forming operation; and

Figure 5 is a detail showing a can nozzle as finished in such dies.

As shown in Figures 1 and 2, the lower die structure is mounted on the usual die shoe 6 which may be of any ordinary or preferred form of construction in order to.

adapt it to the press. An outer die member 7 is secured to the shoe in any desired manner, as by means of screws 8. Its upper surface is preferably provided with a projection 9 so that the die is adapted to conform to the outer surface of the can top 10 which is first formed as shown in Figure 3 preparatory to the operation of these dies.

central die member or forming punch 11 is' lower end of the tapered portion 14. Below the shoulder 15 is another tapered or conical ortion 16 which conforms to the inner surface of the completed spout or nozzle, as

mately the same diameter as the opening through the nozzle or slightly larger than the diameter of the projection 16.

nozzleis to be forme The can top or metal late 10 in which the is first shaped as shown in' Figure 3 with a substantially cylrndr cal projection 19 having an inwardly pro ecting rim or flange 20. This blank is placed over the upper end 14 of the unch which fits closely in the hole in the lank' with the flange 20 resting on the shoulder or projection 15. As the die 17 moves downwardly, it presses the blank down so that the flange 20 is bent upwardly against the ad acent surface of the partially formed nozzle 19 as shown in dotted lines in Figure 3. Thereupon the further downward movement of the die 17 causes this partially formed bead 21 to engage with the conical or tapered section 16 which forces the bead outwardly so that it projects beyond the adjacent portion of the nozzle 19, leaving a substantially smooth inner surface in the nozzle. The continued downward movement of the blank causes the nozzle to be forced outwardly to conform with the conical section 16, as shown in Figure 4 so that the nozzle is tapered to adapt it for receiving a tapered cork or plug 22, as shown in Figure 5. As the blank moves downwardly, the outer surface of the bead 21 contacts with the adjacent inner slightly tapered wall 23 of the die 7 in order to complete the formation of the bead or so that the inner edge will be pressed closely against the adjacent portion of the nozzle.

From this description, it will be seen that I provide a novel die which is adapted to comlcte or form ahead which is made by turnlng the edge of the nozzlihwardly instead of outwardly, as is the common practice. While such nozzles may be made of any suitable material, in those which I have made, the sheets are of approximately 22 to 24: gauge sheet steel and it would be impossible or impractical to form a bead of such material by turning the edge of the nozzle outwardly in the usual manner. Having thus described my invention, what I claim and desire to secure by' Letters Patent is:

1. A die of the character set forth comprising an outer hold-down portion with a substantially conical recess therein and a central forming punch in fixed relation thereto' and pro ecting outwardly through said recess, said punch having an upper tapered end with an outwardly extending shoulder at the bottom of the same and having a second therethrough of slightly lar er tapered portion of larger diameter and tapering 1n the same direction as the tapered end below the shoulder conforming to the the inner surface of the article to be formed and a coacting die havin a hole iameter than said shoulder and adapte to press the article to be acted upon over the unch and against the outer hold-down portion.

2. A pair of dies for making articles of the character set forth, comprising a lower I die member having an outer portion with its up er surface shaped to conform to the blank and having a central forming punch, said central punch having a projection adapted to engage with a flange on the blank for turning the same upwardly, and an upper die adapted to coact with the lower die and having a central opening of slightly larger diameter than said projection.

3. A die for forming can nozzles, comprising an outer portion having a central recess in the upper surface thereof, a forming punch projectin upwardly from said outer portion, an annu ar shoulder for engagement with a flange on the blank to be formed, said punch also havin a ta red portion below the shoulder whic is a apted to coact with the adjacent wall of the outer die member for finishing-the nozzle, and an upper die member for pressing the blank downwardly onto the first named die.

4. The combination with a die shoe, of a die member 7 having its up er surface shaped to conform with the lank to be acted upon, a punch mounted in said shoe and rojecting upwardly throu h a hole in the ie member, said punch having a shoulder adjacent to the upper end thereof and having a tapered portion of slightl greater diameter than the shoulder below the shoulder, and an upper die member for pressing the blank downwardl over said punch and into engagement wit 'the first named die member.
